LOCK FOR FIRE-ARMS.

SPECIFICATION forniing part of Letters Patent No. 234,749, datedNovember 23, 1880.

' Application filed October 2,1880. (Model) To all whom it may concern:

Be it known that 1, ALEXANDER T. BnowN, of Syracuse, in the county ofOnondaga and State of New York, have invented certain new and usefulImprovements in Looks for Fire- Arms, and that the following, inconnection with the accompanying drawings, is a full descriptionthereof.

My invention relates particularly to locks for three-barreled guns ofthe character described in H. Bakers Patents, Nos.l67,293, dated the31st day of August, 1875, and 198,333, dated the 18th day of December,1877, in which a rifle-barrel is arranged below and between the barrelsof a double-barreled shotgun and it consists of an inside hammer pivotedin the trigger-plate and working between the side locks, and providedwith means by which itmay at pleasure be connected with 20 the tumblerof one of the side locks, and thus be operated by the maiuspring of saidside lock; or, when so connected and it is found desirable to fire theshot-barrel first, that it may be easily disconnected. In this manner 25 I simplify the look by dispensing entirely with the mainsprin g, asear, and sear-spring for the lock of the rifle-barrel.

Referring now to the drawings, Figure 1 is a side view of the frame ofthe gun with the o right-hand lock removed, showing the mechanism of theleft-hand and inside locks. Fig. 2 is a view of the inside hammer and.its pivoted hook; and Fig. 3 is a View of the lower part of the outsidehammer and its tumbler. 3 5 a indicates the outside hammer; b, itstunibler; c, an arm projecting from said tumbler Z), and provided at itsend with a projecting pin or screw, d. c is the inside hammer, pivotedin an opening in the trigger-plate, as 40 shown in Fig, 1, and fis ahook pivoted to said hammer e in rear of the pivot of the latter. j isthe comb or finger-piece of the hammer e, which extends below thetrigger-plate, and by which the hammer c is cocked. m is a 5 link towhich the mainspringgof the side lock is connected, the lower end ofsaid link'being connected to the tumbler b in the manner described in W.H. Bakers Patent, No. 199,7 73, dated the 29th day of January, 1878. iisthe sear which engages with the tumbler Z). 70 is a spring, arranged onthe under side of the tang of the frame so as to bear on the hammer eand hold it by frictional contact either in its cooked or uncookedposition, so as to secure certainty of action.

The operation of this mechanism is as follows: When it is desired tofire the rifle-barrel the outside hammer is first full-cocked. By thisoperation the arm 0 is carried down into a position to be engaged by thehook f.

The hammer e is then cocked by pressing against the finger-piece j. Inthis operation the pivotal point of the hook is carried down ward, andthe rear edge or side of said. hook comes in contact with the end of theopening in which the hammer is pivoted, and is thereby turned forward soas to bring the hook in the line of travel of the pin 61 on the arm 0,and these parts are engaged and the hammer e is carried forward by theforce of the main- 7o spring g, and caused to strike its firing-pin.

The length of the hook f is such that when the hammer e is arrested thehammer on will not have finished its stroke, and will be prevented fromstriking its firing-pin, and the rifle-barrel will alone he fired. When,however, it is desired to tire the shot-barrel the hammer c is notcocked, and the hook will then not engage the arm 0, and then hammer towill be free to fall, or, the hammers having been brought intoengagement with each other, they may be disconnected by letting thehammer a down and then recocking it. This will leave the hammer c in itsuncooked position, and the hook will not engage the arm 0 when thehammer to is discharged.

It is evident that instead of relying on the end of the opening in thetrigger-plate to move the hook into position to engage the arm 6, a pinor stud may project from the lock-plate, and that the arm 0 may bearranged on the tumbler of either of the sidelocks.

Having thus described my invention, what I claim as new is- 1.. In agun-lock of the character described, 9 5 the combination of an insidehammer pivoted in the tri gger-plateand provided with a pivoted book, asshown, and the hammer and tumbler of the side lock, the parts being'arranged to be as described, whereby either the inside or outeonneetedand disconnected substantially in side hammer may be actuated by thesame ro the manner and for the purpose described. mainspring, asdescribed.

2. The combination of the; hammer a and tumbler I), provided with arm 0and pin d, the ALEXANDER BROWN hammer e and its pivoted hook f, arrangedto Witnesses be connected with and disconnected from the L. 0. SMITH,arm 0 and pin 41 in the manner substantially GEO. LIVERMORE.
